Abstract
A method of performing passive packet cross-checking of flooding packets within a multi-node system is disclosed. A first flooding packet is transmitted from a communication node to a first additional communication node of the multi-node system. The first flooding packet causes the first additional communication node to transmit a second flooding packet based on the first flooding packet to the communication node and to a second additional communication node of the multi-node system. A copy of the first flooding packet is stored in a memory cache of the communication node. The second flooding packet is received at the communication node from the first additional communication node. The second flooding packet and the stored copy of the first flooding packet are compared at the communication node, and a status of the first additional communication node is determined based on the comparison.
